Your HVAC system does more than heat and cool.
It filters what you breathe.
Indoor air can be dirtier than the air outside. We help North Shore homeowners breathe easier with filtration, purification, humidity control, and fresh-air ventilation that work with your heating and cooling system.
The problem with tight homes
Weatherization improves efficiency. It can also trap indoor air pollutants.
EPA studies consistently show indoor air can be two to five times more polluted than outdoor air. Modern construction and aggressive weatherization reduce infiltration—which saves energy but also keeps dust, dander, mold spores, VOCs, and humidity inside. The solution isn't to seal less aggressively. It's to ventilate and filter intentionally.
- Dust and particulates — from cooking, pets, textiles, and outdoor air infiltration
- Pollen and mold spores — especially during Chicago's high-pollen seasons
- VOCs — from paints, cleaning products, furniture off-gassing, and cooking
- Excess humidity in summer — promotes mold growth and dust mite populations
- Insufficient humidity in winter — dries out mucous membranes and wood surfaces
- Stale air — CO₂ builds up in tightly sealed rooms over hours
Our IAQ solutions
Filtration, ventilation, and humidity control—integrated with your existing system.
Media filtration
High-MERV filtration for your existing system
We upgrade standard 1-inch filters to high-efficiency 4- or 5-inch media filters that capture particles as small as 0.3 microns—including fine dust, pollen, pet dander, and mold spores. Unlike low-quality HEPA filters, properly sized media filters don't restrict airflow or strain your blower.
- MERV 11–16 filtration, captures particles down to 0.3 microns
- Sized and installed to maintain proper static pressure
- Replace once per year instead of monthly
UV air purification
Germicidal UV light for your air handler
UV-C lamps installed in your air handler neutralize airborne bacteria, viruses, and mold spores as air passes through the system. Most effective when combined with media filtration—the media captures particles while UV neutralizes biologics that pass through.
- Effective against viruses, bacteria, and mold spores
- Installed inside the air handler—no ozone byproduct
- Low maintenance: lamp replacement every 1–2 years
Honest guidance— not every home needs every product.
How we think about it
Start with filtration — The single highest-impact upgrade for most homes is moving from a basic 1-inch filter to a properly sized high-MERV media filter. It captures particles your existing filter misses, and it doesn't require any new equipment, just a filter housing upgrade. This is the right first step for almost everyone.
Add humidity control if you have dry winters — If you run your heat all winter and notice static electricity, dry skin, or cracking wood, a whole-home humidifier will make a noticeable difference. It's also one of the simpler, more cost-effective IAQ upgrades, and it integrates cleanly with any forced-air system.
Consider ERV for tight new construction — If your home is new, recently heavily weatherized, or has been tested at under 3 ACH50, you likely need mechanical ventilation. An ERV is the right tool: it provides continuous fresh air without the energy waste of exhaust-only ventilation.
Add UV if biology is a concern — UV air purifiers are most valuable for households with mold sensitivity, allergy sufferers, or anyone concerned about airborne pathogens. Pair them with high-MERV filtration for maximum effectiveness; the two systems target different categories of contaminants.
Our approach — We start with the basics, look at how your home is built and how you live in it, then recommend only the upgrades that actually solve a problem. Sometimes that means a simple filter change; sometimes it means a full IAQ plan. Either way, the goal is a healthier home without unnecessary gear.
